DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The technical contents of this disclosure will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.

[0016] With reference to FIGS. 1 and 2 for an exploded view and a perspective view of a liquid cooling heat sink structure and its cooling circulation system of this disclosure respectively, the cooling circulation system comprises one or more liquid cooling heat sink structures, and the heat sink structure provided for passing through a cooling liquid (not shown in the figure) comprises a thermal conduction module 1, and a liquid supply module 2.

[0017] The thermal conduction module 1 comprises a thermal conductive substrate 10, and a plurality of fins 11 installed on the thermal conductive substrate 10. The bottom of the thermal conductive substrate 10 is provided for contacting a heat source 5 (as shown in FIG. 4 or 5), and the heat source 5 may be a central processing unit (CPU), a graphic processing unit (GPU), or any other heat generating electronic component or chip, and the thermal conductive substrate 10 conducts the heat to the fins 11 for heat dissipation or cooling.

[0018] The liquid supply module 2 is installed on the thermal conductive substrate 10. With reference to FIG. 3 for a preferred embodiment of this disclosure, the liquid supply module 2 includes a casing 20 having a containing space 200 formed therein. When the casing 20 is installed on the thermal conductive substrate 10, the fins 11 of the thermal conduction module 1 are situated in the containing space 200 and provided for entering the cooling liquid into the containing space 200, and the fins 11 are provided for carrying the heat absorbed by the cooling liquid, so as to achieve a good cooling effect by using the cooling liquid.

[0019] With reference to FIGS. 1, 2 and 3 for a liquid cooling heat sink structure of this disclosure, the liquid cooling heat sink structure has a continuous surrounding peripheral wall 201 formed on the liquid supply module 2 and continuously surrounding a surrounding surface of the casing 20 and oriented in a plurality of directions facing towards the outside of liquid supply module 2. More specifically, in a preferred embodiment of this disclosure, the peripheral wall 201 is in a rectangular shape which is corresponsive to the shape of the casing 20 and at least has a first wall 202 and a second wall 203, and the first and second walls 202 are opposite to each other and oriented in different directions facing the outside of the liquid supply module 2. In the meantime, the peripheral wall 201 has at least two first liquid opening 21, 22, and a second liquid opening 23, and the first liquid opening 21, 22 and the second liquid opening 23 are communicated with the containing space 200 of the casing 20, and the first liquid opening 21, 22 are disposed at positions on any two different facing surfaces of the peripheral wall 201. In a preferred embodiment of this disclosure, the two first liquid opening 21, 22 are disposed on the first wall 202 and the second wall 203 respectively. Since the first and second walls 202, 203 are opposite to each other, therefore they are configured in different directions facing the liquid supply module 2. In other words, the two first liquid opening 21, 22 formed on the first and second walls 202, 203 respectively are naturally disposed at positions of different facing surfaces.

[0020] This disclosure further comprises a plug member 3 selectively installed on any first liquid opening 21, 22 to seal the first liquid opening 21 or 22. Therefore, the heat sink structure may be used according to the connecting position of the pipeline, and the liquid opening 21, 22 or 23 may be used as liquid inlets or outlets (such as the two first liquid opening 21, 22 being liquid inlets, and the second liquid opening 23 being a liquid outlet; or the two first liquid opening 21, 22 being liquid outlets, and the second liquid opening 23 being a liquid inlet), and one of the two first liquid opening 21, 22 is selected for use, and the other first liquid opening 22, 21 is sealed by the plug member 3, so as to provide the effect of configuring the heat sink structure more flexibly.

[0021] By the aforementioned components, the liquid cooling heat sink structure of this disclosure is formed.

[0022] In addition, this disclosure further provides a cooling circulation system. With reference to FIG. 4 for a cooling circulation system in accordance with the first preferred embodiment of this disclosure, the cooling circulation system comprises at least two heat sink structures, and a water-cooled exhaust 6, and the two heat sink structures and the water-cooled exhaust 6 are connected in series. Wherein, any one of the first liquid opening 21 of the two heat sink structures is sealed by the plug member 3, and the other first liquid opening 22 and the second liquid opening 23 are connected by a pipe connector 4, so that the connecting pipeline 60 connects the two heat sink structures and the water-cooled exhaust 6 in series. Now, the second liquid opening 23 and the other a first liquid opening 22 connected to the pipe connector 4 are disposed on different facing surfaces (or situated on the first wall 202 and the second wall 203 of the peripheral wall 201 respectively; in other words, the first liquid opening 21 connected to the plug member 3 and the second liquid opening 23 are disposed at positions of different facing surfaces respectively).

[0023] With reference to FIG. 5 for a cooling circulation system in accordance with the second preferred embodiment of this disclosure, the cooling circulation system is connected to the two heat sink structures and the water-cooled exhaust 6 in parallel. Wherein, any one of the first liquid opening 22 of the two heat sink structures is sealed by the plug member 3 and the other first liquid opening 21 and the second liquid opening 23 are connected by a pipe connector 4, so that the connecting pipeline 60 connects the two heat sink structures and the water-cooled exhaust 6 in parallel. Now, the second liquid opening 23 and the first liquid opening 21 connected with the pipe connector 4 are disposed on the same surface (or the first wall 202 of the peripheral wall 201).

[0024] By the aforementioned components, the cooling circulation system of this disclosure is formed.

[0025] In summation of the description above, the liquid cooling heat sink structure and its cooling circulation system in accordance with this disclosure are novel and inventive and comply with patent application requirements, and thus this disclosure is filed for patent application.

[0026] While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
